Explanation
A transaction has issued a request to a coupling facility data table for which it holds an active lock, but after the lock was acquired, the coupling facility data table server for the pool in which this coupling facility data table resides failed and was restarted. This request is of a type which cannot continue against a new instance of the server, because it is reliant on the lock which was acquired before the server failed.
System action
The requesting transaction abends with a transaction dump.
CICS continues normally.
User response
Retry the failed transaction.
